6 DBG - Debug Interface
6.1 Introduction
6.2 Features
6.3 Functional Description
6.4 Debug Lock and Device Erase
2010-09-06 - d0001_Rev1.00
The EFM32G devices include hardware debug support through a 2-pin serial-wire debug interface. In
addition there is also a 1-wire Serial Wire Viewer pin which can be used to output profiling information,
data trace and software-generated messages.
• Flash Patch and Breakpoint (FPB) unit
• Data Watch point and Trace (DWT) unit
• Instrumentation Trace Macrocell (ITM)
There are three debug pins on the device, which also can be used as GPIO. The three debug pins are:
• SWCLK Serial Wire Clock input. This pin is enabled after reset and has a built-in pull down.
• SWDIO Serial Wire data Input/Output. This pin is enabled after a reset and has a built in pull-up.
• SWO Serial Wire Viewer Output. This pin is disabled after a reset.
For more information on how to enable the debug pin outputs/inputs the reader is referred to
Section 28.3.2.1 (p. 394) , the ARM Cortex-M3 Technical Reference Manual and the ARM CoreSight
Technical Reference Manual
The debug access to the Cortex-M3 is locked by clearing the Debug Lock Word (DLW), see
Section 7.3.2 (p. 29)

• Implement breakpoints and code patches
• Implement watch points, trigger resources, and system profiling
• Application-driven trace source that supports printf style debugging

What?
The DBG (Debug Interface) is used to
program and debug EFM32G devices.
Why?
The Debug Interface makes it easy to re-
program and update the system in field, and
allows debugging with minimal I/O pin use.
How?
The Cortex-M3 supports advanced
debugging features. EFM32G devices
only use two port pins for debugging or
programming. The systems internal and
external state can be examined with debug
extensions supporting instruction or data
access break- and watch points.
